济阳坳陷及鲁西隆起区中、新生代伸展与断裂活动特征
|
摘要
济阳坳陷与鲁西隆起具有相同类型的结晶基底。选取这两个地区近年来3条有代表性的大跨度深层反射地震剖面,重建盆地沉积岩层埋藏史,通过反复拟合盆地内部构造形态,定量计算各主要构造演化阶段的构造运动学参数,详细解析了基底伸展变形过程。结果表明济阳坳陷与鲁西隆起区基底伸展及断裂活动在时空上很不均衡,两个地区古近纪伸展变形强度均显著大于中生代;古近纪济阳坳陷南北向地壳伸展率和伸展速率均为东西向的两倍以上。
Jiyang depression and Luxi uplift share the same type of crystalline basement.Three typical deep seismic reflection profiles acquired in these two regions during recent years were used to reconstruct the depositional burial history of the basin.By repeatedly matching the tectonic features of the basin,kinematic parameters during each main tectonic evolution stage were quantitatively calculated and the extensional process of the basement was analyzed in detail.The results show that both basement extension and fault activity are in temporal and spatial non-equilibrium in Jiyang depression and Luxi uplift,and the intensity of extensional deformation during Paleogene is much stronger than that during the Mesozoic for both of the regions.For Jiyang depression,both the ratio and rate of the Paleogene extension in N-S direction are two times bigger than those in E-W direction.This article provides an important basis for the further study of the tectonic evolution and crustal extensional deformation of the Great North China in Eastern China during the Meso-Cenozoic.
